von Peter himself shares some of his treasured links.
As is the way with the transcience that is the internet one cannot rely on what is here and present today will still be there and present tomorrow. Apologies in advance if a link is presented but now no longer works. All that von Peter himself can offer up in compensation is the cold comfort statement that the link worked when it was added. Maintenance of the links will be undertaken ... however sporadically that may be.
